Switch zoning limitations for the Hitachi TagmaStore AMS 2000 family of systems
There are limitations in switch zoning for the Storwize® V3500 system and the Hitachi TagmaStore AMS 2000 family of systems.
Switch zoning
Members of the Hitachi TagmaStore AMS 2000 family of systems present themselves to the Storwize V3500 clustered system as separate storage systems for each port zoned to the Storwize V3500 system. For example, if one of these storage systems has four ports zoned to the Storwize V3500 system, each port appears as a separate storage system rather than one storage system with four WWPNs. In addition, a given logical unit (LU) must be mapped to the Storwize V3500 system through all storage system ports that are zoned to the system that use the same logical unit number (LUN).
